NOZZLE FOR DEPOSITING-MACH INES.

SPECIFICATION forming part of Letters Patent No. 651,829, dated June 19,1900.

Application filed November 6, 1 89 9.

To all whom it may concern:

Be it known that I, ALEXANDER W. P- LAND, a citizen of the UnitedStates, residing at Boston, Suffolk county, Massachusetts, (post-officeaddress, 252 Massachusetts avenue, Boston, Massachusetts,) have inventedcertain new and useful Improvements in Nozzles forDepositing-lylachines, of which the following is a specification.

In certainof the arts there are employed machines designed to deal atone timewith two different kinds of plastic material and deposit one ofthe materials in certain relationship to the other. An example is foundin the depositing machines employed in making cakes and confectionery.(See, for instancsa, my Patent No. 544,962, of August 20, 1 95. i

My present invention relates to improvements in the depositing-nozzlesfor suchmachines regardless of the. material with which they areintended to deal or the product which they are designed to produce; butfor purposes of description I will assume the improved nozzle to beemployed in the'production of cakes or the like formed of dough incombination with jam, it being understood that in this description Iemploy the terms dough and jam as merely illustrative of dissimilarplastic materials to be dealt with by the nozzle.

My invention will be readily understood from the following description,taken in connection with the accompanying drawings, in which Figure 1 isa side elevation of a depositingnozzle exemplifying my invention; Fig.2, a vertical longitudinal section thereof in the plane of line a ofFig. 3, this view alsq comprehending a typifying surface or plate toreceive the deposit from the nozzle; and Fig, 3, a horizontal section ofthe nozzle in the plane of line b of Figs. 1 and 2. p In the drawings, 1indicates a chamber into which dough may be forced under controlledpressure; 2, the supply-conduit leading thereto; 3, achamber into whichjam may be forced under controlled pressure; 4, the supply-conduitleading thereto; 5, a fixed casing containing the chambers l and 3 andhaving the conduits 2 and 4 communicating with it; 6, a plug screwedupwardly into the casing 5;

7, the upper end of plug 6, the same fitting chamber 3 is around theupper neck of the plug; 8, an annular groove cut upwardly in the base ofplug 6, the roof of this groove separating the groove from chambers 1and 3; 9, a series ofvertical ports in plug 6, leading through the roofthereof and placing groove 8 in free communication with doughchamber 1and its conduit 2, the illustration showing five of these ports; 10, avertical central bore in plug 6, the sameextending up to near the top ofthe plug; 11, a series of radial ports extending through the neck of theplug and placing counterbore 10 in free communication with jam-chamber 3and its conduit 4, the illustration showing five of these radial ports;12, a contracted nozzle at the base of counterbore 10; 13, a cylindricalvalve-rod projecting down through the roof of chamber 1 and through theroof of couniterbore 10, in both of which roofs it fits nicely and isadapted to project into and fill the contracted nozzle 12 of counterbore10, this valve- 'rod being adapted for vertical motion, so as ,zle12,-sufficient space being formed between the two nozzles to permit aproper flow of the dough from groove 8 to nozzle 15, and 16 anexemplifying pan, plate, or surface on which the nozzles may delivertheir deposits.

Referring to Fig. 2, let it be assumed that conduit 2 is arranged toconvey dough under controlled pressure and that conduit 4 is arranged toconvey jam under controlled pressure, as is common indepositing-machines, as illustrated, for instance, in my earlier patentabove referred to. Assume valve-rod 13 to be in the position shown inthe drawings. The

dough from conduit 2 will fill chamber 1 and pass through ports 9 andinto annular groove 8 and will become expelled through nozzle 15 in theform of a rope of dough. Assume plate 16 to be absent. Then this rope ofdough will continue to pass from nozzle 15 and may be dealt with asdesired, being cut ofi in short pieces orbeing cut ofi in long piecesand coiled up, as desired. Under such conditions the product of thenozzles may be described as a continuous rope of dough. Again, assumethe conditions as before, but with plate 16 present. The rope of doughwill start down from nozzle 15, and upon striking plate 16 it willbecome flattened or swelled out into cake form. If now thesupply-pressure on the dough be arrested and the plate 16 be lowwardlywith the plate, leaving the cake united to the nozzle by a neck formedby the rope of dough; but as the descent of the cake continues the neckwill become stretched and attenuated and finally assume a thread-likethinness and break, the stalagmite, so to speak, of doughcollapsing intothe cake, while the stalactite ofdough depends from the nozzle; Theplate being presented upwardly anew to the nozzle condenses thestalactite of dough, and then when the pressure of dough is reinstalledthe formation of another cake begins, and: so on, as before. Under theseconditions the product of the nozzle may be described as cakes of doughupon a receiving surfaceto be; lifted free of nozzle 12 and assume thedough and jam as being supplied under pres sure. The jam coming throughconduit 4 will enter chamber 3 and pass through radial ports 11into-counterbore 10 and out of nozzle12 at the same time the dough ispassing out of nozzle 15,. The jam passes centrally down, from nozzle 12through nozzle 15, while the dough passes annularly down through nozzle15 around the rope of jam. Under such conditions, assuming plate 16 tobe absent, there will pass continuously from nozzle 15a rope of doughhaving a core of jam, and this compound product thus passingcontinuously from the nozzles may be cut off and dealt with as desired.The product of the nozzles in such case may be described as a continuousrope ofdough havingacontinuous jam core. Again, assume valve-rod 13 inclosed position, as seen in Fig. 2, and assume pressure upon the supplyof dough, under which conditions the rope of dough starts out of nozzle15. The rope of dough having thus started, let valve-rod 13 be raised,thusopening nozzle 12. The two materials will thus flow together, therope of dough having a'ja'm core, the lower end of the compound ropebeing sealed by dough. If the pressure be arrested and the compound ropecut olf, there will result apiece of rope having its lower end andperiphery formed of dough, its core being formed of jam-in other words,a deep.

c'up forrnedlof' dough and filled to the top with jam. It underconditions similar to, the

above the compound rope be permitted to come against the plate 16, itwill become swelled out and. enlarged, and when the rope is cu-t olfthere will obviously result a cup of dough having a contracted form andfilled with; jam exposed at the top.

sume that the rope of dough is started and Again, assume valve-rod '13,

Again, as-' then the core of'jam is started and that then valve-rod 13is lowered, thus arresting the flow of jam, while the flow of doughcontinues for a period, the flow of jam being later and at intervalsrepeated as the flow of dough continues. The product will be a rope ofdough containing within it at intervals completely-inclosed bodies ofjam. If during ,each cessation of the flowof jam the rope of ered, thecake upon the plate will move downdough be cut oif, there will result aseries of short sections of dough rope each containingacompletely-inclosed body of jam. Again, assume the rope of dough to bestarted and to come against plate 16, whereupon the dough begins toswell outward into cake form. At the same time let the flow of jam bestarted by raising valve-rod 1 3, thus de= positingjam within the cake.Then let the flow of jam be arrested, and let the flow of dough continuefor an interval, The result will be that the rope of dough will re-formsolidly-over the deposited jam. If new theflow of dough is stopped andthe" plate be lowered, the neck uniting the cakewith' the nozzle will bethinned and finally severed,

thus leaving upon the platea cake of dough containing acompletely=incliosed body of jam, the inclosing wall, of dough beingwithout seam or joint of any character; Again, assume the rope of doughto be started against plate 16 and that the plate is carriedhorizontally as the rope is deliverednpon it. The result will be thatthe rope will lie upon the plate in flattened form. 'While this istaking place the flow of dough maybe ar rested at intervals, thusdelivering upon the plate a series of flattened long-cakesof dong-h Atthe same time while'each cake of dough is thus being formed upon theplate there may be injected into it a body of jam, thus producing longfiat cakes of dough containing completely-inclosed bodies of jam.

The above examples are simplyillustrative of the variety of productsobtainable from the nozzle. Heretofore attempts have been made toproduce similar results by central jam-nozzles whose cessation of actiondepended upon cessation of pressure upon the jam supplemented in casesby a sucking action upon the jam; but these attempts have not beensuccessful, owing to the fact that the flow of jam was notsatisfactorily cut oif, the result being that the closure of the doughabove the jam necessarily partook of the nature of awelding' or contactaction,
